Abstract

fetched live from OpenAlex

Background: Nut consumption is associated with a reduced risk of coronary heart disease (CHD). Almonds, in addition to their cholesterol‐lowering properties, have been shown to reduce oxidized LDL concentrations. However, their effect on other markers of lipid peroxidation is unknown. Methods: Twenty seven men and women with hyperlipidemia consumed 3 iso‐energetic (mean 423 kcal/d) supplements as part of their therapeutic diets for 1 month each. Supplements consisted of full‐dose almonds (73±3g/d), half‐dose almonds plus half‐dose muffins and full‐dose muffins. Subjects were assessed at wks 0, 2 and 4. Results: At 4 wks, the full‐dose almonds significantly reduced serum concentrations of malondialdehyde (MDA) (P=0.040) and creatinine‐adjusted urinary isoprostane output (P=0.026) compared to the full‐dose muffins. No effect was seen in serum levels of α‐ or γ‐ tocopherol, adjusted or unadjusted for total cholesterol. Conclusion: Almond consumption significantly decreased oxidative damage to 2 additional biomarkers of lipid peroxidation, serum MDA and urinary isoprostanes, further supporting our previous finding that almonds reduced the oxidation of LDL. This provides a further mechanism, in addition to cholesterol‐lowering, that may account for the reduction in CHD risk associated with nut consumption. Funding support: Almond Board of California

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
